Mencap, the UK's leading charity for children and adults with a learning disability, wants you to sign up for its biggest challenge to date, an 11-day, 325km bike ride in Brazil.

From August 17 to 27 you will ride your bike from San Paulo to Rio de Janeiro with a series of stunning stop-off points en route. Marvel at the beautiful colonial city of Ouro Preto, pedal your way down the old cobbled road to Rio and enjoy a final celebratory day on Copacabana beach.

Other highlights of the trip include a visit to a school for children with learning disabilities in Congonhas and an overnight stay in a monastery.

If you want to take part, all you have to do is pay a £299 registration fee and raise a minimum sponsorship requirement, then travel, food and lodgings are included.
